OWINGS MILLS, Md. — Going into what will be most starters’ final preseason tuneup on Saturday night, the Ravens are banged up along the offensive line.

Left tackle Ronnie Stanley left Monday’s game in Indianapolis with what was labeled a minor knee sprain, and the versatile James Hurst quietly exited before fellow interior starters Matt Skura and Alex Lewis and was not present for Wednesday’s practice. The potential absence of both Stanley and Hurst — who has served as the backup left tackle in past seasons — could complicate Baltimore’s plans against Miami, and that’s not even considering the status of right guard Marshal Yanda, who is practicing but has yet to play in the preseason after undergoing offseason shoulder surgery.

Should those three not play against the Dolphins, it’s fair to wonder whether head coach John Harbaugh would alter his plans for quarterback Joe Flacco’s playing time.

“It’s always a part of the decision-making,” offensive coordinator Marty Mornhinweg said. “However, it is football. And I’ll tell you what, with a backup man that’s fighting for a starting job, a good strategy is to put him in with the rest of the ‘ones’ and see how he does rather than put him in with the ‘twos’ or ‘threes.’ Sometimes you can’t get quite the evaluation, so there are a couple of those things that may happen as well.”

Rookie sixth-round pick Greg Senat has worked as the second-team left tackle in the preseason while Hurst has practiced at either right guard or right tackle. A former basketball player at Wagner, the 6-foot-6, 305-pound Senat is an intriguing prospect, but his lack of experience would be less than ideal protecting Flacco’s blindside this close to the start of the season.

Senat missed the start of training camp and the Hall of Fame Game with a lower leg injury before returning to practice in early August.

“Greg was hurt for a period of time,” Mornhinweg said. “The really good thing is — and we’ve had several players do this that have come in; they don’t have much work under their belt, but they’re getting better every day. He got better from last week to this week. That’s a good thing, and let’s see how far he can go in the next two weeks.”

Hurst’s absence could increase the likelihood of rookie third-round pick Orlando Brown Jr. beginning the season as the starting right tackle.

Returner competition

Monday wasn’t a banner game for return specialists Tim White and Janarion Grant, who each lost a fumble against the Colts, but the Ravens aren’t giving up on their potential.

Whether that means either makes the 53-man roster remains to be seen.

“They have the duty to the rest of the team to protect the football, and they know that,” special teams coordinator Jerry Rosburg said. “It’s two young players that got in situations where they didn’t realize that they needed to practice the ball-security habits that they both have. They have those skills, and in both those situations, they need to lock the ball down and they didn’t. Hopefully, the lesson has been learned.”

Ideally, one of the two would seize the job and be able to provide a spark in the field-position game, but the Ravens could elect to just go with established veterans better trusted to secure the ball. Wide receiver Chris Moore served as the primary kick returner for much of last season, but not a single player to return a punt last season remains on the roster, leaving less clarity for that role.

Slot receiver Willie Snead has fielded plenty of punts during spring and summer workouts, but he fumbled his only career punt return for New Orleans last season.

“He’s been efficient. He’s in every meeting. He’s locked in,” Rosburg said. “He comes out here and practices well, and we’ll see how it plays out down the road. Again, we still have two preseason games left, so we want to give those other guys an opportunity to show what they can do.”

Mornhinweg concerned with Jackson taking hits

More than a few observers have expressed concerns about the number of hits taken by rookie quarterback Lamar Jackson in the preseason, a sentiment shared by Mornhinweg.

Shoddy pass protection from reserve offensive linemen has led to Jackson being sacked six times, but the former Heisman Trophy winner has taken multiple hits in the open field in lieu of trying to protect himself. It’s understandable for a rookie to be eager to make plays — especially playing before a national audience in two of the first three preseason games — but the Ravens clearly want him to stay healthy to continue his development.

“Yeah, that’s not good. You see what I’m saying? It’s just that simple,” Mornhinweg said. “Between the numbers, now, we want to get down underneath the hits unless you think you can score and typically you’re one-on-one. Outside the numbers, we want to get up and get out. And we’d rather get down a step too early than a step too late or get up and out a step too early than a step too late.

“That’s an ongoing process. Some of it is experience because he does have to filter through exactly what he can get away with and what he can’t in this league. It’s a little different situation here, a little different league, a little different speed, a little different quickness — all those things.”

Wednesday attendance

In addition to Stanley and Hurst, running back Kenneth Dixon, tight end Mark Andrews, defensive backs Maurice Canady and Bennett Jackson, and linebacker Alvin Jones did not participate in Wednesday’s practice.

Harbaugh noted after Monday’s game that Dixon was still not 100 percent after dealing with a hamstring injury for a large portion of camp. The third-year running back drew praise in his preseason debut by collecting 56 total yards on his nine touches, his first live-game action since 2016.
